Given the following coded blood relationship definitions:
- $A \star B$ means ' $A$ is the mother of $B$ '
- $A \sharp B$ means ' $A$ is the brother of $B$ '
- $A \dagger B$ means ' $A$ is the daughter of $B$ '
- $A \Delta B$ means ' $A$ is the father of $B$ '

Based on the expression $K \star L \sharp M \dagger N \Delta P$ , how is $P$ related to $K$ ?

A
Son
B
Daughter
C
Mother
Cannot be determinedCevap

Cevap

Cannot be determined (the person is either the son or the daughter)

Deconstructing the relation expression shows that

K

(mother) and

N

(father) are married parents of

L

M

, and

P

. Because no operator defines whether

P

is male or female,

P

could be either a son or a daughter of

K

. Therefore, the exact relation cannot be determined uniquely.

Adım Adım Çözüm

Decode the first part of the expression:

K \star L \sharp M

K

is the mother of

L

, and

L

is the brother of

M

. Therefore,

K

is the mother of both

L

and

M

Siblings share the same parents.

Decode the next part:

M \dagger N

M

is the daughter of

N

. Since

K

is already established as the mother of

M

N

must be the father of

M

(and husband of

K

A child has one male parent (father) and one female parent (mother).

Decode the final part:

N \Delta P

N

is the father of

P

. Since

N

and

K

are the parents of

L

and

M

P

is also a child of

K

and

N

Children of the same father belong to the same sibling group.

Determine the gender of

P

The operator

\Delta

indicates that

N

is the father of

P

, but gives no information regarding

P

's gender.

P

can be male or female.

Gender must be explicitly stated and cannot be assumed.
